  /* Notes on the implementation
   *
   * The implementation is based on dynamically resizable arrays of points and
   * flags. I dithered for a bit before deciding on this implementation, and
   * I had even done a bit of work on a linked list version before switching
   * to arrays. It's a bit of a tradeoff. When you use linked lists, the
   * implementation of FlattenPath is easier, because you can rip the
   * PT_BEZIERTO entries out of the middle of the list and link the
   * corresponding PT_LINETO entries in. However, when you use arrays,
   * PathToRegion becomes easier, since you can essentially just pass your array
   * of points to CreatePolyPolygonRgn. Also, if I'd used linked lists, I would
   * have had the extra effort of creating a chunk-based allocation scheme
   * in order to use memory effectively. That's why I finally decided to use
   * arrays. Note by the way that the array based implementation has the same
   * linear time complexity that linked lists would have since the arrays grow
   * exponentially.
   *
   * The points are stored in the path in device coordinates. This is
   * consistent with the way Windows does things (for instance, see the Win32
   * SDK documentation for GetPath).
   *
   * The word "stroke" appears in several places (e.g. in the flag
   * GdiPath.newStroke). A stroke consists of a PT_MOVETO followed by one or
   * more PT_LINETOs or PT_BEZIERTOs, up to, but not including, the next
   * PT_MOVETO. Note that this is not the same as the definition of a figure;
   * a figure can contain several strokes.
